26.2 - 18.5 = 7.7. I used subtraction to figure out how many more miles she needs to run each day to reach her goal. 
She needs to run 7.7 more miles a day to reach her goal. 

I hope this helps!

What would be the equation for #23???
Rufina [12.5K]
Hi there!

Let r be the number of matches that Rebecca's team won.

We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.

Using this given information, we can create the following equation.

r+9=52

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

r=43

Have an awesome day! :)

Both angles are complementary and add up to 90 degrees. If you do that in an equation it should be like this:

2x + 14 + x + 7 = 90

Simplify:

3x + 21 = 90
3x = 69
X = 23

Now just plug that into angle CBD and you get:

2(23) + 14 = y
46 + 14 = y
60 = y

Angle CBD is 60 degrees

Answer:

  4. height: 5√3 cm; area: 25√3 cm²

  5. 30√2 ft ≈ 42.43 ft

Step-by-step explanation:

4. The height of an equilateral triangle is (√3)/2 times the side length, so is ...

  height = (√3)/2 × (10 cm) = 5√3 cm

The area is given by the formula ...

  A = 1/2bh

  A = 1/2(10 cm)(5√3 cm) = 25√3 cm²

__

5. The diagonal of a square is √2 times the side length, so the distance from 3rd to 1st base is ...

  (30 ft)√2 ≈ 42.43 ft

__

The length of the diagonal of a square is something you should be familiar with. If you're not, you can figure the distance using the Pythagorean theorem.

  d = √(30² +30²) = √1800 ≈ 42.43 . . . feet
